Black Pearl initial rent commencement
Company: Cipher Mining - Project: Black Pearl Facility
What the later record shows
Delivered on time · happened July 31, 2026
A July 2026 lease amendment moved first capacity delivery up to July 31, 2026, ahead of the October 2026 target. A later news piece says the facility came online early and is earning rent, but it relies on social media commentary rather than a company statement that rent began.
“On July 24, 2026, we amended the HPC lease at the Black Pearl Facility, which accelerated delivery of the first capacity to July 31, 2026.”
